It take 18 hours to fly by plane from Melbourne, Australia (MEL) to Denver, CO (DEN)

18 hours + $100k even = $118k. Since Mr. Cruel hails from Australia and was returning there shortly, he had no intention of collecting on that money. Similar to his previous crimes, he made ransom demands but did not collect. He also had no reason to remove the body from the home after he got his satisfaction. He knew from Karmein Chan that the family would be the subject of investigation if he did.

Mr. Cruel did not need to know John Ramsey's bonus to arrive at that number.
